Technical field

Present invention relates in general to be used for traction belt and the endless track on the tracklaying vehicle.The present invention especially but not exclusively, relate to the traction belt and the endless track that are used on agricultural, building industry, forestry vehicle and other the similar tracklaying vehicles.

Background technology

The vehicle of many types often is used in and is difficult to use on the airtyred landform.The for example military-designed vehicle of tank and individual armored motor car and the for example civil car of trac. and recreational vehicle all move on very soft landform such as husky surface.Air-inflation tyre can not effectively move on such pressure release surface usually, crosses because air-inflation tyre usually is absorbed in this surface rather than on this surface.

The tracklaying vehicle that is used on the landform that wheeled car can't go, using is developed.Be 3,361,488,3,688 for example referring to the patent No., 858,3,734,577 and 3,955,855 US Pat.The performance of these vehicles on the landform of many types is superior to the performance of wheeled car.But existing tracklaying vehicle still is faced with problem.

Originally, tracklaying vehicle has the crawler belt of being processed by a plurality of metallic bonds or aglet, thus the attached pivotally each other formation endless track of these metallic bonds or aglet.

Nowadays, it is more general that resilient track becomes, and this is to increase because of what build in the urban area, and tracklaying vehicle must go on the road surface that making is crossed in the urban area, also is because of the growth of requirement to the low agri-vehicle of soil compaction degree.

Along with the development of elastic traction band and endless track, designed the external screw-thread pattern that is applicable to various landform in a large number.For example, some thread pattern of specific crawler belt have big earthed surface, and this surface is more suitable for being used in such as on pitch and the concrete crust, but the tractive force that should the surface on the pressure release surface such as soil and sand, provides is little.The thread pattern that is applicable to pressure release surface also is developed, but they do not possess extraordinary durability usually on crust.

Agri-vehicle and other crawler type farming with vehicle such as trac. on, use a kind of thread pattern and this thread pattern consistent with the chevron pattern haply usually.This specific thread pattern provides enough tractive forces usually on most of landform, this is very important for agri-vehicle.Yet because the structure of chevron, conventional chevron thread pattern is faced with such problem usually: thus need more energy to make the crooked rolling resistance that increased of crawler belt also finally increase fuel discharge.

People have attempted to reduce makes the crooked required energy of the endless track with chevron thread pattern roughly.Be that the traction lugs that forms chevron has otch in 6,241,327 the US Pat in the patent No., this otch can open when crawler belt is crooked.Yet these otch have obviously reduced traction lugs and have reduced the structure integrity of crawler belt thus, and finally can only produce limited effect.Be that the chevron thread pattern is formed by some independently traction lugs in 6,510,913 the US Pat in the patent No..Through the chevron thread pattern is divided into some traction lugs, the contact surface of traction lugs generally reduces, and has therefore increased level of vibration.

Therefore, need a kind of improved traction belt that reduces the defective of traction belt in the prior art.

Summary of the invention

The present invention reduces defective of the prior art through providing a kind of improved elastic traction to bring generally.This traction belt generally includes the master tape body, and this master tape body is divided into a plurality of band sections, and these band sections (usually integrally) are attached together along the nodel line of horizontal expansion, and the longitudinal extent of each band section is commonly called pitch.Said belt body have be suitable for its on the nearside wheel mating surface that various wheel the (for example sprocket wheel, (one or more) idle pulley and/or (one or more) bearing wheed) of the caterpillar system of said traction belt matched is installed, and be suitable for ground, the outside mating surface with ground engaging.

The said mating surface of taking turns comprises a row or arranges longitudinally-spaced driving lug (and/or guide lug) more that said driving lug (and/or guide lug) typically, is somebody's turn to do the length setting of band along the length setting of this band in each band section upper edge.Continuous driving lug (and/or guide lug) is not had the horizontal expansion region separation that drives lug (and guide lug) to be opened, and aligns with nodel line in fact in said horizontal expansion zone.

Said ground mating surface comprises traction lugs, and some said traction lugs longitudinal extensions stride across a more than band section.The traction lugs of these longitudinal extensions advantageously comprises the bending area of horizontal expansion, and is thinner in said bending area traction lugs.These bending areas roughly align with nodel line, and therefore with said inside face on nothing drive the region alignment of lug (and guide lug).

Preferably, the thickness of said bending area is the part of the thickness of said traction lugs.

Preferably but not exclusively, said traction lugs limits the chevron thread pattern in fact.

The person skilled in the art will easily understand that the region alignment of the said nothing driving lug (and guide lug) on said thin bending area and the said inside face has reduced that each takes turns bending or the required energy of the said traction belt of warpage around caterpillar system.Therefore, thus traction belt of the present invention has reduced rolling resistance has also reduced fuel discharge.

In addition, with respect to prior art traction lugs is separated fully, said thin bending area has kept the substantial continuity and the structure integrity of traction lugs, thereby has kept the distinctive advantage of traction lugs (for example soil rubble removing, tractive force etc.).

The characteristic that is considered to have novelty among the present invention will be set forth in appended claim.
